Expression of concern for ‘One-pot synthesis of O-doped BN nanosheets as a capacitive deionization electrode for efficient removal of heavy metal ions from water’ by Ming Ming Chen et al., J. Mater. Chem. A, 2017, 5, 17029–17039.
BNO nanosheets could capacitively remove multiple metal ions from water due to their unique structural characteristics and coordination ability.
In this study, a spherical Fe/C composite (AIBC) was successfully prepared via carbonization of Fe3+-crosslinked sodium alginate.
